Who's your daddy?

Now casting male role models for 'Gossip Girl'

"Gossip Girl's" Serena van der Woodsen, subject to a rotating cast of stepfathers and more than a few liaisons of her own, surely could use a strong male role model in her life. Enter Billy Baldwin.

Baldwin is set to play William van der Woodsen, the biological father of Blake Lively's Serena, for a few episodes starting in April. Eonline.com predicts Mr. van der Woodsen blows into town to stir things up with his ex-wife, Lily, who's been a little too blissed-out with her new husband, Rufus.

We're all for the return of Baldwin,arguably the most stable among his famous brothers, to prime time, where we haven't seen him since ABC canceled his short-lived "Dirty Sexy Money" last summer.

Still, Upper East Side society is competitive, and we have to consider other casting options. And, this being "Gossip Girl," any of these suggestions also could serve as Serena's next stepfather. ARIEL ALEXOVICH, REDEYE

Neil Patrick Harris

Sure, NPH is a little young to have a college-age daughter, but he and Serena would thrive as the blonder, campier answer to the "Gilmore Girls."

Jack Donaghy

Alec Baldwin's zany "30 Rock" character already lives in Manhattan, so it'd be easy to do a crossover episode. And if this leads to some kind of throwdown between Blair Waldorf and Kenneth the Page, so be it.

Quentin Tarantino

"Gossip Girl" is high drama. So is the manic Tarantino. We can't really imagine what it'd be like if those worlds collided, but it would probably involve a LOT of blood.

Derek Jeter

Beautiful, rich Serena always has been the girl who has everything. It would be just like her for her dad to be a superstar New York Yankee.

Ernie Lively

Blake's real-life dad already played her father in both "Sisterhood of the Traveling Pants" movies. Not that "Gossip Girl" is at all based on reality, but at least they'd have that genetic thing going on.
